Essential Programs To Have

[Vega]

1. Lavasoft Adaware (or another program that can find and delete spyware)
Where to get: Lavasoft.de OR you can find the professional version for free off suprnova.tk.
What it does: Finds spyware and other crap on your computer that you don't want. Good idea to get even if your computer is fine, and especially good to get when its running slow and you're getting more pop ups than usual.

2. Pop-up stopper
Where to get: panicware.com
what it does: stops pop ups. it stops about 99% sucessfully in my experience. some people have a hard time finding this, just look around on the site for a free version. It's like with Hotmail how when you sign up for an e-mail they have all this crap to get you to try and buy the pay version, where theres a little link at the bottom to get the free version.

Feel free to add your own.
